TOBACCO-PIPE.

SPECIFICATION formingpart of Letters Patent No. 480,570, dated August 9,1892.

Application filed July 15, 1891- Serial No. 399.625. (N0 model.)

To all whom it may concern.-

Be it known that I, THOMAS T. ELY, of West Paris, in the countyof Oxfordand State of Maine, have invented a new and useful Tobacco-Pipe, ofwhich the following is a full, clear, and exact description.

As usually constructed the draft is downward through the charge oftobacco in a pipe, and all smoke evolved by combustion of the tobacco isdrawn through it, which has a tendency to render the smoke strong andacrid, that results from burning the lower portion of the charge oftobacco, and injurious, owing to the precipitation of nicotine from theburning portion upon the part of the charge below the point of ignition.

The object of this invention is to provide a tobacco-pipe which shall befree from the obj ectionable feature above mentioned and that willafford means to consume a charge of tobacco within the pipe by itscombustion near the top of the tobacco-holding chamber and permit theuser of the pipe to draw the smoke resulting from such combustionthrough a passage exterior of said chamber.

To this end my invention consists in the peculiar construction andcombination of parts, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal axial section of a tobacco-pipe containingthe improvement. Fig. 2 is a transverse section of the pipe-bowl and theimprovement therein, taken on the line 2 2 in Fig. 1; and Fig. 3 isalongitudinal axial section of the pipe-bowl and stem broken and theimprovement within adjusted to receive a charge of tobacco.

The pipe-bowl A and its stem B may be made of any suitable material,there being a mouth-piece 0 provided, which is removably attached to thestem in the usual manner. There is a cavity a formed in the pipe-bowl A,of a proper depth and diameter, which is intersected by the longitudinalbore b of the stem B near the bottom of the cavity, said bore being bypreference made of a larger diameter than is the smoke-passage c in themouth-piece 0. Within the cavity a a tobacco-holding cup D isintroduced, which is preferably formed of sheet metal having acylindrical side wall and a flat bottom d. The relative diameter of thecup D to the cavity a is such as will permit an annular space a tointervene between of sufficient width to form a draft-passage for smoke.

The upper edge of the cylindrical wall of the cup D is radiallyprojected a proper distance to afford a horizontal flange e, that isdownwardly bent near its outer edge, as at e, said depending portionbeing made to fit against the exterior of the pipe-bowl A with a nearlyair-tight joint, the wall of the bowl having a taper upwardly ofsufficient degree to allow the cup to be readily withdrawn from thepipe-bowl.

A circular diaphragm-plate E is inserted within the cup D, fitting thesame loosely, so as to slide freely, which plate forms a false bottomfor the cup, that is maintained near the upper edge of the latterbyavolute spring F, which is seated upon the fixed bottom 0?, and whencollapsed by pressure on the plate E will permit said diaphragm-plate toapproach near to the fixed bottom.

At a short distance from the upper edge of the holder-cup D, atevenly-spaced intervals, the side wall of said cup is perforated, as atg. Preferably four small apertures or draftholes g are provided, anddirectly above two of these holes, which are diametrically opposite eachother, a small inwardly-projecting lip h is formed close to and aboveeach hole, which lips from their position and formation are adapted tohave contact with the charge of tobacco that is placed within the cup D,near its upper surface, and thereby hold the diaphragm-plate Edepressed.

In use there is a charge of smoking-tobacco inserted in the holder-cup Dand sufficiently compacted to depress the diaphragm-plate E near thefixedvbottom d, the spring F by com pression having its energy stored tobe exerted upon the plate and charge of tobacco through the stem andmouth-piece. The tobacco from its consistency is held within the cup Dby its engagement with the lips h, and as the ashes resulting from thecombustion of the tobacco are destitute of fiber or coherent strength itis evident that the progress of combustion will permit the charge oftobacco in the cup to be raised as it is consumed until the cup isnearly empty.

As the smoke from combustion of tobacco in the mproved pipe is drawnlaterally from the portlon ignited,itisnotbroughtin contactwith theunburned part of the charge in the cup D. Hence the smoke is of equalflavor during the combustion of an entire charge of tobacco. Anycondensation resulting therefrom being caught in the cavity a below thecup may be quickly removed by disconnection of the holder and limited inits outward movement 30 by said projections, substantially as set forth.
